I can't identify your pro em, but I have had problems with 2 things: web page being too big causing transmission problems, especially on esp32s2 and the other is uninitialised strings causing random initialisation errors. Typically, in my case, it has been a program bug. I would suggest that your refresh request is not processed as input.
